Just updated to latest build and I'm not liking the new UI. A common action for me to it select some of the spam emails that make it through or other marketing emails and just delete them. It was quite easy in previous UI.
In new UI, first I have to open Select menu and then choose "Enable Select Mode". Then I have to click on three dots (actions menu) and choose "Delete" - which btw is right next to "Delete All in Folder", so a disaster waiting to happen.
My recommendations:
1. Replace "Select" Menu with an icon button that enables select mode.
2. Bury the "Select all" and "Deselect All" actions in actions menu, as I don't really see the need for Selecting all Emails regularly? Delesecting all can be accomplished by turning off Select Mode or using the "Deselect All" option in actions menu.
3. Add delete button on toolbar as well, so that its easy to select multiple emails and just hit delete button.
4. Add option in settings to switch email list to paginated view. Scrolling list is way too slow when using on desktop (in a browser). With paginated view, I can guestimate and switch multiple pages quickly when trying to find some old email.
